Navigation System: Description and Operation: Overview

Navigation System

OVERVIEW
The navigation system provides audible and visual route guidance information to enable the driver to reach a desired destination. The system allows the driver to choose the route using minor or major roads or highways with the option of three routes. Directions to hospitals, museums, monuments and hotels are also available.
The navigation system is integrated with the audio/video system and shares a number of components common to all systems. Map information is stored on a hard disk drive located in the Integrated Audio Module (IAM). Map upgrades to the hard drive can be uploaded by the customer from a Universal Serial Bus (USB) memory stick (not applicable to Japan/Asia specification vehicles).
The navigation system uses the following components:
- Integrated Audio Module (IAM)
- Integrated Control Panel (ICP)
- Dual-view Touch Screen Display (TSD)
- Sigma pod for GPS antenna
- Instrument cluster.
The dual-view TSD allows the front seat passenger to view television and video images when the car is being driven. The dual-view screen allows the driver to see the navigation or other system screens but not the TV or video when the vehicle is moving. The screen can be switched between single and dual view using a switch on the ICP.

NOTE:
Due to legislation, the NAS markets do not receive this dual-view option.
Japanese market vehicles have a modified system from other markets. These vehicles have an additional navigation computer module and a navigation video interface module located in the luggage compartment. Japanese specification vehicles are also fitted with Vehicle Information and Communication System (VICS) beacon antenna, which is located on the top of the instrument panel.
